Effects of weather and climate on interconnected wetland-upland landscapes; effects of various forms of global change on ecoregional landscape dynamics and landscape-biodiversity interactions.

Dr. Alisa Gallant is a Research Physical Scientist with the U.S. Geological Survey's Earth Resources Observation and Science (EROS) Center. She directs and conducts integrated interdisciplinary studies that incorporate remote sensing, GIS/geospatial modeling, landscape characterization, and ecoregional analyses, from global to local scales. Dr. Gallant has been involved with integrated landscape research since the early 1980s, initially with the U.S. Environmental Protection Agency for water quality issues across the conterminous United States, then later with the Landscape Biodiversity Laboratory at Montana State University to analyze landscape-biodiversity relations in the Greater Yellowstone Ecosystem, and finally with USGS/EROS. Since joining EROS, Dr. Gallant served as the lead geographer for the USGS Amphibian Research and Monitoring Initiative for eight years and currently is the remote sensing and geospatial analysis lead for the Terrestrial Wetland Global Change Research Network.

Measurements integrated across data from ground and satellite sensors provide a fuller understanding for how climate interacts with environmental settings to influence land-cover responses in interconnected wetlands and uplands.
